A doctor can tell if a person has abnormal breath sounds by listening with a stethoscope. This is often seen in people with COPD or Asthma.
Crackles
Air is normally able to pass through the bronchial tree normally is the bronchial tree is open via laminar flow. Breath sounds are heard during auscultation of the chest, using a stethoscope. Normal breath sounds are termed as vesicular breath sounds. However, in conditions such as a pleural effusion where there is air within the pleural cavity, the flow of air becomes disturbed. Therefore, there will be absent breath sounds and if the effusion is large, bronchial breath sounds will be heard which are both abnormal.
You do not "read" a stethoscope. It is a device that allows medical personnel to hear sounds within the body. Areas of sounds you can hear with a stethoscope include:heart soundsarterial sounds, such as a bruit (an abnormal sound)breath sounds (lungs)bowel sounds
no breath sounds
Adventitious sounds are sounds that you hear that are not normal sounds of inspiration and expiration. Examples are 1. rales, crackles and crepitations; 2. wheeze; 3. stridor; 4. pericardial friction rub; 5. rhonchi.
Crepitus.Abnormal crackling sounds are called rales when heard on ausculation of the lungs, but called crepitus when heart in a joint, gangrenous skin, etc.
Rhonchi is the medical term meaning abnormal snoring sounds when breathing.
Abnormal sounds may be heard before, after, or during the normal heart sounds. For instance, sounds associated with stenosis may be heard before the closing of that valve.
Alcohol in breath dissipates quickly but not in urine, where it can be detected for about three days.
The anterior chest is the most common place to auscultate for abnormal heart sounds. Some abnormal sounds may also be heard in the center of the back or in the neck.
Cough, fever, sputum production, difficulty breathing, chest pain.Findings may include abnormal breath sounds, hypoxia, tachypnea, tachycardia, fever, hypotension (if in severe sepsis), and an infiltrate on xray.Shortness of breath, fever, cough with sputum production, and decreased energy.
Stethoscopes can detect bodily sounds such as breath, cardiac, and abdominal sounds. In the hands of a skilled professional they can be used to detect abnormal heart sounds, bruits, and carotid blockages.
